Yes if you miss the right point the thc trich pop and break down meaning the strength goes way down. Early harvest gets a more heady buzz and if you max it you get a more hard core stone..If you over wait then it goes weak, looks bad, tastes worse and you can get mold and loose weight.
No offense, but nothing you said even remotely makes sense.
True, THC does have a "pinnacle", where it has reached its maximum level in the plant. So does CBD, CBN, CBC, THCV, and the other dozens of cannabinoids the plant produces. What you failed to mention is, when THC starts to degrade, it degrades into CBN, or Cannabinol. CBN is an extremely psychoactive cannabinoid, and in many cases, growers cure their herbs for months to maximize the possible conversion of THC to CBN. Also, CBD takes longer for the plant to synthesize, and high THC levels aren't necessarily what some people are looking for. Some people would much prefer ripening a Cataract Kush, for example, to 17% THC, 1.4% CBD, and .5% CBN, as opposed to cutting the same plant a week earlier, which would have yielded results such as 19% THC, 0.8% CBD, and .1% CBN. In other words, the effect of the cannabis depends on much more than just THC content alone. The process I just explained for cannabinoid synthesis fully explains why earlier plants give you a heady buzz, while later plants give you a heavier stone, although genetics of course play a huge role in the cannabinoid profile as well.
All of the herb that I have ever seen get over-ripened looks absolutely phenomenal, and smells and tastes even better. The only thing that might be minimized is the psychoactive effect of the THC, which could very well be offset by other valuable cannabinoids. It makes no sense, scientifically, for herb to smell worse when it is more ripened. Just think about the function of terpene production in general. Terpenes and resins are produced in nature to maximize a plants life cycle, so it can survive as long as possible. Once a plant produces terpenes, they don't magically evaporate. They never, however, completely stop producing terpenes, as long as proper photosynthesis is occuring.
The presence of mold has nothing to do with the maturity of a plant. And the assumption that plants can lose weight if left to long is just....Well I won't even respond to that. Just wanted to correct a misrepresented fact or two.
